             (v)   Customer shall use reasonable efforts to forecast Product
       needs on a reasonably uniform basis throughout each Contract Year.
       [CONFIDENTIAL TREATMENT REQUESTED]

       (c)   ROLLING [CONFIDENTIAL TREATMENT REQUESTED] OPERATIONS SCHEDULE.
Customer and Catalytica shall collaborate in good faith to maintain an ongoing
"Rolling [CONFIDENTIAL TREATMENT REQUESTED] Operations Schedule", which shall be
provided by Catalytica on a monthly basis commencing [CONFIDENTIAL TREATMENT
REQUESTED] and shall cover a period of approximately [CONFIDENTIAL TREATMENT
REQUESTED]. The Rolling [CONFIDENTIAL TREATMENT REQUESTED] Operations Schedule

shall communicate and cooperate in good faith to ensure that such document is as
accurate and up-to-date as possible.

       (d)   NOTIFICATIONS REGARDING [CONFIDENTIAL TREATMENT REQUESTED] AND
[CONFIDENTIAL TREATMENT REQUESTED]. The Parties shall use good faith to
determine the [CONFIDENTIAL TREATMENT REQUESTED] and [CONFIDENTIAL TREATMENT
REQUESTED] obligations applicable to particular periods under Section (b) (ii)
and (b) (iii) above. If either Party hereto determines that the other Party may
breach an obligation related to the [CONFIDENTIAL TREATMENT REQUESTED] or
[CONFIDENTIAL TREATMENT REQUESTED] the Party who makes such determination shall
notify the other Party as soon as reasonably practicable. The Party who is
believed to be in danger of breaching its obligation hereunder shall be provided
a reasonable opportunity to correct its forecast, schedule, or other intended
course of action so that it may avoid such breach, and the other Party hereto
shall use reasonable efforts to allow and accommodate such correction. In the
event that the Parties disagree on the calculation of the [CONFIDENTIAL
TREATMENT REQUESTED] or [CONFIDENTIAL TREATMENT REQUESTED] applicable to
[CONFIDENTIAL TREATMENT REQUESTED] time period, the Parties shall negotiate in
good faith to resolve any such disagreement.

       6.2   [CONFIDENTIAL TREATMENT REQUESTED]

       (a)   [CONFIDENTIAL TREATMENT REQUESTED].

             (i)   In the event that Customer does not meet its [CONFIDENTIAL
       TREATMENT REQUESTED] for a particular [CONFIDENTIAL TREATMENT REQUESTED]
       period, [CONFIDENTIAL TREATMENT REQUESTED], provided, however, that
       Customer shall receive a credit for components purchased during such
       [CONFIDENTIAL TREATMENT REQUESTED] period in accordance with Section 7.
       Each Kit of Product shall be valued at [CONFIDENTIAL TREATMENT
       REQUESTED]. Catalytica shall, within [CONFIDENTIAL TREATMENT REQUESTED]
       following the end of each [CONFIDENTIAL TREATMENT REQUESTED] Firm Order
       period, invoice Customer for any amounts owed under this Section
       6.2(a)(i). Customer shall pay such invoice within [CONFIDENTIAL TREATMENT
       REQUESTED] of the date of receipt thereof. If Customer has been given
       credit for the purchase of any Kits or Kit components during any
       [CONFIDENTIAL TREATMENT REQUESTED] period, such credit shall be
       applicable to that [CONFIDENTIAL TREATMENT REQUESTED] period.

             (ii)   Notwithstanding the foregoing, Customer may, with
       Catalytica's consent, which shall not be unreasonably withheld,
       substitute another Customer product that has been developed, tested,
       manufactured and marketed by Customer in order to meet the [CONFIDENTIAL
       TREATMENT REQUESTED] hereunder; PROVIDED, HOWEVER, that (A) any such
       substitute product is reasonably comparable to the Product and the timing
       requirements of any substitute Product are practicable, (B) [CONFIDENTIAL

                                       13

       TREATMENT REQUESTED], and (C) the Parties shall negotiate in good faith
       to determine (i) that price will be paid to Catalytica for such
       substituted product, and (ii) the extent to which the quantities of
       substituted product shall be deemed to substitute for the Product
       included in Firm Orders and/or Semi-Firm Orders hereunder.

       (b)   [CONFIDENTIAL TREATMENT REQUESTED]. For each relevant [CONFIDENTIAL
TREATMENT REQUESTED] period, Catalytica shall be obligated to supply up to the
[CONFIDENTIAL TREATMENT REQUESTED] of Product, as further described in Section
6.1(b)(ii) and (b) (iii) above. In the event that Customer presents total Firm
Orders or Semi-Firm Orders for Product for a particular [CONFIDENTIAL TREATMENT
REQUESTED] period that exceed the [CONFIDENTIAL TREATMENT REQUESTED] specified
in Section 6.1(b)ii or (b)iii above, Catalytica shall use its commercially
reasonable efforts to supply the excess quantity by adjusting its schedules and
making any other commercially reasonable accommodations. If Catalytica is able
to supply such excess quantity, the parties shall agree in writing on a new
[CONFIDENTIAL TREATMENT REQUESTED] for such time period.

       (c)   BATCH FAILURES. In the event that any run results in nonconforming
Product for which Catalytica bears liability under the Agreement, such failed
Batch shall be counted in determining whether the [CONFIDENTIAL TREATMENT
REQUESTED] has been met hereunder, but such failed Batch shall not be counted in
determining whether the [CONFIDENTIAL TREATMENT REQUESTED] has been exceeded
hereunder.

                         PURCHASE OF PRODUCT; DELIVERIES

       7.1   PURCHASE ORDERS. Except to the extent the Parties may otherwise
agree with respect to a particular shipment, the Product shall be ordered by
Customer pursuant to written purchase orders (a "Purchase Order"), which shall
be sent to Catalytica [CONFIDENTIAL TREATMENT REQUESTED] specified in such
Purchase Orders. [CONFIDENTIAL TREATMENT REQUESTED]. Upon receipt by Catalytica
of each Purchase Order hereunder which conforms in substance and procedure to
the requirements of this Agreement, which Purchase Order may, but is not
required to specify Labeled Kit components by lot number, Catalytica shall
supply and deliver Product in accordance with such Purchase Order and this
Agreement. If such Purchase Order identifies Labeled Kit Components by lot
number, Catalytica shall, [CONFIDENTIAL TREATMENT REQUESTED], notify Customer as
to whether Catalytica agrees with such identification. Notwithstanding
Customer's rights under Section 7.5 hereof, if Catalytica determines that
[CONFIDENTIAL TREATMENT REQUESTED] any requested delivery of Product will be
delayed [CONFIDENTIAL TREATMENT REQUESTED] beyond the Delivery Date set forth in
the Purchase Order, Catalytica shall so advise Customer, and as to any delayed
delivery which results from an Unexcused Failure, Catalytica shall use its best
commercial efforts to deliver the remaining portion of such Purchase Order
quantity as quickly as possible after any such delay. As to each Purchase Order,
if Labeled Kit components have not been identified by lot number, [CONFIDENTIAL
TREATMENT REQUESTED], Catalytica shall identify by lot number proposed Labeled
Kit components to be used in filling such Purchase Order. Customer shall have
the right to approve the proposed components, which approval shall not be
unreasonably

withheld. Except as specified above, once received by Catalytica, Purchase
Orders are firm and may not be cancelled or modified without Catalytica's prior
consent.

       During the initial Contract Year, in the event that Customer withdraws a
Purchase Order upon [CONFIDENTIAL TREATMENT REQUESTED], Customer shall be
responsible for and shall reimburse Catalytica for [CONFIDENTIAL TREATMENT
REQUESTED]. Customer may withdraw a purchase order upon [CONFIDENTIAL TREATMENT
REQUESTED] and Catalytica in good faith shall use commercially reasonable
efforts to obtain projects or other work for the production time otherwise
specified for Customer's Product. In such event, Customer shall be liable
[CONFIDENTIAL TREATMENT REQUESTED].

       7.2   PURCHASE QUANTITIES. All Product shall be ordered in Labeled Kits
or Unlabeled Kits, or if necessary to meet Customer's other contractual
obligations, individual components. Each Purchase Order shall specify the
quantity of Kits or components being ordered. Quantities actually shipped
pursuant to a given Purchase Order may vary from the quantities reflected in
such Purchase Order [CONFIDENTIAL TREATMENT REQUESTED] and still be deemed to be
in compliance with such Purchase Order; provided, however, Customer shall only
be invoiced and required to pay for the quantities of Product which Catalytica
actually ships to Customer.

       7.3   DELIVERY TERMS. The terms of delivery for the Product shall be
[CONFIDENTIAL TREATMENT REQUESTED] Catalytica's Greenville, North Carolina

Product in accordance with the Quality Agreement to such designations chosen by
Customer to the extent such shipments are permitted by Applicable Laws and
Regulations related thereto. In the event Customer requests that the Product be
shipped to a third party purchaser, such third party shall have all approvals
under Applicable Laws and Regulations to receive, use and/or sell the Product.
Customer and, as applicable, such third party purchaser will prepare, obtain,
and maintain all necessary import and export registrations relating to the
Product and the IDEC Ingredients. Customer represents and warrants that it will
comply with all applicable import and export laws and regulations. Catalytica
shall cooperate with the Customer by preparing and filing any necessary
documents to support the Customer's import and export applications.

       7.5   MATERIAL SUPPLY FAILURE. In the event of a Material Supply Failure,
Customer shall provide Catalytica written notification of such Material Supply
Failure. Upon Customer's provision of such notice to Catalytica, [CONFIDENTIAL
TREATMENT REQUESTED]

       If a Material Supply Failure occurs during the term of this Agreement,
and subsequent to the occurrence of such Material Supply Failure, [CONFIDENTIAL
TREATMENT REQUESTED]

       7.6   UNBALANCED ORDERING/PRODUCTION. The Parties acknowledge that
Customer may ask Catalytica to produce volumes of different vial sizes or types
of Product and to store such

                                       15

                                                CONFIDENTIAL TREATMENT REQUESTED

vials and/or types for later incorporation into kits or for shipment in another
mutually agreed form. The Parties further acknowledge that Catalytica has
limited storage space for Product, that such storage (and the delay in shipping
Product and receiving payment) has a cost, and that the retention of Product in
storage may change performance obligations. Catalytica shall store Product, if
so requested by Customer, [CONFIDENTIAL TREATMENT REQUESTED]. Pursuant to
Article 3 hereof the Parties shall in good faith establish procedures for
designating Product to be stored by Catalytica, the conditions for such storage
and the responsibilities and liabilities of the Parties as to Product so stored.

       8.4   TAXES. The Product Price set forth in Exhibit 1 does not include
sales, use, consumption, or excise taxes of any taxing authority. The amount of

shipment thereof and [CONFIDENTIAL TREATMENT REQUESTED]. Customer shall pay the
amount of such taxes to Catalytica in accordance with the payment provisions of
this Agreement.

       8.5   ADDITIONAL PAYMENTS. As additional consideration for Catalytica's
performance of its obligations hereunder, Customer shall pay Catalytica the
amounts set forth below (with all payments being due [CONFIDENTIAL TREATMENT

provided below). All invoices shall provide reasonable detail of services
performed and costs incurred.

       8.6   METHOD OF PAYMENT. At the time of each shipment of Product
hereunder, Catalytica shall invoice Customer, and Customer shall pay for such
Product [CONFIDENTIAL TREATMENT REQUESTED] of receipt of each such invoice. All

       Catalytica and Customer each shall notify the other promptly if any Batch
of Product is alleged or proven to be the subject of a recall, market withdrawal

of example exchanging relevant data and, if applicable, relevant data from
IDEC's licensee. In the event of a disagreement as to any matters related to
such recall, market withdrawal or correction, other than the determination of
who shall bear the costs as set forth in the immediately following sentence,
Customer shall have final authority with respect to such matters, as described
in the Quality Agreement. Customer shall bear the cost of all recalls, market
withdrawals or corrections of Product unless such recall, market withdrawal or
correction shall have been the result of Catalytica's negligence, willful
misconduct or breach of this Agreement, in which case Catalytica shall bear the
direct cost of administering such recall, market withdrawal or correction.
[CONFIDENTIAL TREATMENT REQUESTED]. Customer shall maintain records of all sales
of Product and customers sufficient to adequately administer a recall, market
withdrawal or correction for a period of [CONFIDENTIAL TREATMENT REQUESTED]

be responsible for interactions with FDA or other governmental authorities that
conduct or request any recalls, market withdrawals or corrections with respect
to the Product.

either Party in the event of the material breach (including without limitation
the occurrence of a Material Supply Failure) or default by the other Party of
the terms and conditions hereof; provided, however, the other Party shall first
give to the defaulting Party written notice of the proposed termination or
cancellation of this Agreement, specifying the grounds therefor. Upon receipt of

to respond by curing such default [CONFIDENTIAL TREATMENT REQUESTED] or
[CONFIDENTIAL TREATMENT REQUESTED] by delivering to the other Party a
certificate that such breach is not capable of being cured within such

diligently to cure such breach, but in no event shall the time period for curing
such breach exceed an additional [CONFIDENTIAL TREATMENT REQUESTED], unless
otherwise agreed to in writing by the Parties. If the breaching Party does not
so respond or fails so to work diligently and to cure such breach within the
additional time set forth above, then the other Party may either suspend the
Agreement indefinitely or terminate the Agreement. Termination of this Agreement
pursuant to this Section 10.4 shall not affect any other rights or remedies
which may be available to the nondefaulting Party.

                                 INDEMNIFICATION

       12.1   INDEMNIFICATION BY CUSTOMER. Customer shall indemnify, defend and
hold Catalytica, its Affiliates and their respective directors, officers,
employees, agents, successors and assigns harmless from and against any damages,
judgments, claims, suits, actions, liabilities, costs and expenses (including,
but not limited to, reasonable attorneys' fees) arising out of or connected with
Third Party claims relating to [CONFIDENTIAL TREATMENT REQUESTED].

       12.2   INDEMNIFICATION BY CATALYTICA. Except as otherwise provided in
Section 12.1 above, Catalytica shall indemnify, defend and hold Customer, its
Affiliates and their respective directors, officers, employees, agents,

       12.3   INDEMNIFICATION PROCEDURES. A Party (the "Indemnitee") which
intends to claim indemnification under this Article 12 shall promptly notify the
other Party (the "Indemnitor") in writing of any action, claim or other matter
in respect of which the Indemnitee or any of its Affiliates, or any of their
respective directors, officers, employees or agents intend to claim such
indemnification; PROVIDED, HOWEVER, the failure to provide such notice within a
reasonable period of time shall not relieve the Indemnitor of any of its
obligations hereunder except to the extent the Indemnitor is prejudiced by such
failure. Prompt or reasonable notice shall depend on the nature of the claim
and/or the circumstances but shall normally be considered as ten (10) business
days from a Party's knowledge of such claim. The Indemnitee, its Affiliates, and
their respective directors, officers, employees and agents shall cooperate fully
with the Indemnitor and its legal representatives in the investigation,
negotiation, compromise, settlement and defense of any action, claim or other
matter covered by this indemnification. The Indemnitor shall be in charge of and
control of any such investigation, negotiation, compromise, settlement and
defense and shall have the right to select counsel with respect thereto,
provided that the Indemnitor shall promptly notify the Indemnitee of all
developments in the matter. In no event shall the Indemnitor or Indemnitee
compromise or settle any such matter without the prior written consent of the
other Party, which shall not be bound by any such compromise or settlement
absent its prior consent, which shall not be unreasonably withheld or delayed.
The Indemnitee shall have the right, but not the obligation, to be represented
by counsel of its own selection and at its own expense.

       12.4   SURVIVAL OF INDEMNIFICATION OBLIGATIONS. The provisions of this
Article 12 shall survive the expiration or termination of this Agreement.

appropriate to fulfill its obligations or exercise its rights under this
Agreement or any rights which survive termination or expiration hereof, each
Party may disclose Confidential Information to its Affiliates, sublicensees,
consultants, outside contractors, clinical investigators or other Third Parties
on condition that such entities or persons agree in writing (a) to keep the
Confidential Information confidential for the same time periods and to the same
extent as each Party is required to keep the Confidential Information
confidential and (b) to use the Confidential Information only for such purposes
as such Party is entitled to use the Confidential Information. Each Party or its
Affiliates or sublicensees may disclose such Confidential Information to
government or other regulatory authorities to the extent that such disclosure
(i) is reasonably necessary to obtain patents or authorizations to conduct
clinical trials with and to market commercially the Product, provided such Party
is otherwise entitled to engage in such activities under this Agreement or (ii)
is otherwise legally required.

       13.3   TERMINATION OF CONFIDENTIALITY AGREEMENT. The Confidentiality
Agreement between the Parties dated March 10, 1998 is hereby terminated. All
Confidential Information disclosed by one Party to the other Party pursuant to

                              INTELLECTUAL PROPERTY

       14.1   CATALYTICA PROPERTY. Customer acknowledges that Catalytica
possesses certain inventions, processes, know-how, trade secrets, improvements,
other intellectual properties and other assets, including but not limited to
procedures and techniques, computer technical expertise, software, and certain
technical expertise and conceptual expertise in the area of drug processing and
manufacturing, which have been independently developed by Catalytica or its
Affiliates without the benefit of any information provided by Customer
(collectively "Catalytica Property"). Customer and Catalytica agree that any
Catalytica Property or improvements thereto which are used, improved, modified
or developed by Catalytica under or during the term of this Agreement are the
product of Catalytica's technical expertise possessed and developed by
Catalytica or its Affiliates prior to or during the performance of this
Agreement and are the sole and exclusive property of Catalytica or its
Affiliates, as the case may be.

       14.2   CUSTOMER PROPERTY. Catalytica acknowledges that Customer possesses
certain inventions, processes, know-how, trade secrets, improvements, other
intellectual properties and other assets, including but not limited to
procedures and techniques, computer technical expertise, software and certain
technical expertise and conceptual expertise in the area of drug development,
which have been independently developed by Customer or its Affiliates without

improvements thereto which are used, improved, modified or developed by Customer
or its Affiliates prior to or during the term of this Agreement are the sole and
exclusive property of Customer or its Affiliates, as the case may be.

       14.3   OWNERSHIP AND RIGHTS TO INVENTIONS AND TECHNOLOGY. Ownership of
all inventions, technology and information, whether patentable or not (other
than those described in Section 14.1, and 14.2 which shall be owned by
Catalytica and Customer, respectively), shall be as follows: owned by Customer,
if conceived, reduced to practice or created solely by Customer and/or its
agents during the performance of this Agreement; or (b) owned by Catalytica, if
conceived, reduced to practice or created solely by Catalytica and/or its agents
during the performance of this Agreement; provided, however, Catalytica shall
grant and hereby grants to Customer a royalty-free, non-exclusive, world-wide,
irrevocable license to practice any such Catalytica-owned technology to
manufacture the Product in Customer-owned or other facilities. If Catalytica's
efforts under this Agreement result in inventions which are jointly owned by
Catalytica and Customer because employees or agents for each of Catalytica and
Customer make inventive contributions thereto, that is employees or agents of
both Parties would be or are properly named as co-inventors under the laws of
the United States on any patent application claiming such inventions, then each
Party shall have full rights to exploit such jointly owned inventions for its
own commercial purposes without any obligation to the other Party. Catalytica
shall be responsible for the costs of filing, prosecution and maintenance for
patents and patent applications on Catalytica's owned technology and inventions
and the Parties shall share equally the patenting costs of any jointly owned
inventions. In this regard, any decision to file for patent coverage on jointly
owned inventions, shall be mutually agreed upon, and the Parties will select a
mutually acceptable patent counsel to file and prosecute applications based on
such joint inventions.

       15.1   EFFECTS OF FORCE MAJEURE. Except as expressly set forth below,
neither Party shall be held liable or responsible for failure or delay in
fulfilling or performing any of its obligations under this Agreement in case
such failure or delay is due to any condition beyond the reasonable control of
the affected Party including, without limitation, [CONFIDENTIAL TREATMENT

shall be obligated hereunder to pay for Product received by Customer in
accordance with the terms hereof, including without limitation of time for
making any such payment. Except as provided below, such excuse shall continue as
long as the Force Majeure Event continues. Upon cessation of such Force Majeure

promptly after the occurrence of the cause relied upon, and upon the giving of
such notice the obligations of the Party giving the notice will be suspended
during the continuance of the Force Majeure Event; provided, however, such Party
shall take commercially reasonable steps to remedy the Force Majeure Event with
all reasonable dispatch. The requirement that the Force Majeure Event be
remedied with all reasonable dispatch shall not require the settlement of
strikes or labor controversies by acceding to the demands of the opposing party.

substantially all of the assets of such Party or the line of business of which
this Agreement forms a part, (b) in the event of the merger or consolidation of
a Party hereto with another company, or (c) to any Affiliate of the assigning
Party. Any purported assignment in violation of the preceding sentence shall be

this Agreement. No assignment shall relieve either Party of responsibility for
the performance of any obligation which accrued prior to the effective date of
such assignment.

       19.4   CONTINUING OBLIGATIONS. Termination, assignment or expiration of

affect, limit or waive such Party's right thereafter to enforce and compel
strict compliance with every term and condition of this Agreement.

       19.6   SEVERABILITY. Each Party hereby expressly agrees that it has no
intention to violate any public policy, statutory or common laws, rules,
